CLASP.

SPECIFICATION forming part of Letters Patent No. 233,099, dated October 12, 1880.

Application filed July 17, 1880.

To all whom it may concern:

Be it known that I, DANIEL A. J oHNsoN, of Boston, county of Sufi'olk, State of Massachusetts, have invented an Improvement in Clasps, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to springclasps more especially designed to grasp and hold a shirtsleeve, and has for its object the production of a cheap and efficient device for that purpose to obviate the use of elastic bands.

For holding up shirt-sleeves it is now customary to employ an elastic band bearing at each end a clasp or fastening; but in this my invention only a single clasp is employed with each sleeve.

Figure 1 represents one of my improved clasps in side elevation, the clasp being closed; Fig. 2, a like view, the clasp being open; Fig. 3, a top view; Fig. 4, a section showing the clasp applied to a part of the sleeve to catch it up and hold the fabric, and Fig. 5 a m0dification.

My clasp is comprised of a piece of sheet metal, a, preferably sheet-steel, curved as at a Fig. 2, bent at one end to form a drum, 1), and at its other end to form an outwardlycurved lip, c, which, when the two ends of the (N0 model.)

clasp are brought together, laps over or extends backward over the end of the drum. When applied to folds e e of the fabric 01 of the sleeve the said folds (see Fig. 4) are held between the drum and lip.

This device in practice is about one inch long and from one-half to three-fourths of an inch from top to bottom, and consequently is unobjectiona-ble as far as size is concerned, and is not bulky on the sleeve.

This clasp is very much cheaper and more simple than other devices or contrivances heretot'ore employed for the purpose.

In Fig. 5 I have shown the lip part as provided with teeth, as it may be, to assist in retaining the clasp in place.

I claim- As an improved article of manufacture, the spring-clasp a, bent as described, and provided with a drum and lip to engage and hold a sleeve, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL A. JOHNSON.
